Which statement is true about function F which is shown in the graph F(x)=-8x^5+4x^3+5x
Answer:
Function F is odd
Step-by-step explanation:
just took the edmuntum/plato test. I included my answer
The function F is an odd function.
What are odd functions and even functions?
A function f(x) is even if f(-x) = f(x), for all values of x in D(f) and it is odd if f(-x) = -f(x), for all values of x. The graph even function is symmetric with respect to the y-axis and the graph of an odd function is symmetric about the origin.
According to the question
Function F(x) = [tex]8x^5+4x^3+5x[/tex]
To check whether function is odd or even
Let x = -x
Now, Substituting -x in f(x)
F(-x) = [tex]8(-x)^5+4(-x)^3+5(-x)[/tex]
i.e
F(-x) = [tex]-8x^5-4x^3-5x[/tex]
or
F(-x) = [tex]-(8x^5+4x^3+5x)[/tex]
F(-x) = - F(x)
As per definition of odd function
if f(-x) = -f(x), for all values of x. it is a odd function
Therefore, it is a odd function
When graph will be plotted
We can observe that symmetry about the origin.
Hence, the function F is an odd function.

how many solution does -3 (4 - 3x) = 9x - 12
Answer: infinite solutions
Step-by-step explanation:
(−3) (4) + (−3) (−3x) = 9x + −12
−12 + 9x = 9x + −12
9x − 12 = 9x − 12
9x − 12 − 9x = 9x − 12 − 9x
−12 = −12
−12 + 12 = −12 + 12

Which methods correctly solve for the variable n in the equation 11−n=−20? Select all that apply. First, add n to both sides. Then, add 20 to both sides. First, subtract n from both sides. Then, multiply both sides by −20. First, add n to both sides. Then, subtract 11 from both sides. First, subtract 11 from both sides. Then, multiply both sides by −1. First, add n to both sides. Then, subtract 20 from both sides.
Answer:
First, subtract 11 from both sides. Then, multiply both sides by −1.
First, add n to both sides. Then, add 20 to both sides.
Step-by-step explanation:
Given equation:
11 - n = -20
Solve for variable n
11 - n = -20
Subtract 11 from both sides
11 - n - 11 = -20 - 11
- n = - 31
Multiply both sides by -1
- n(-1) = - 31(-1)
n = 31
First, subtract 11 from both sides. Then, multiply both sides by −1.
11 - n = -20
11 -n +n = -20 + n
11 = -20 + n
11 + 20 = -20 + n +20
31 = n
First, add n to both sides. Then, add 20 to both sides.
First, subtract n from both sides. Then, multiply both sides by −20.
First, add n to both sides. Then, subtract 11 from both sides.
11 - n = -20
11 - n +n = -20 + n
11 = -20 + n
11 - 11 = -20 + n -11
Not possible
First, subtract 11 from both sides. Then, multiply both sides by −1.
First, add n to both sides. Then, subtract 20 from both sides.
11 - n = -20
11 - n + n = -20 + n
11 = -20 + n
11 - 20 = -20 + n - 20
9 = n - 40

After a rain storm, Lily measures the depth of several puddles in her backyard.
How much deeper was the puddle under the swing than the puddle on the sidewalk?
Answer:
3/4 of an inch.
Step-by-step explanation:
The puddle under the swing was 4 inches deeper than the puddle on the sidewalk after the rainstorm.
depth of the puddle under the swing = "x" inches
depth of the puddle on the sidewalk = "y" inches
Difference = Depth of puddle under the swing (x) - Depth of puddle on the sidewalk (y)
For example, if the depth of the puddle under the swing is 8 inches and the depth of the puddle on the sidewalk is 4 inches, the difference would be:
Difference = 8 inches - 4 inches = 4 inches
Therefore, the puddle under the swing is 4 inches deeper than the puddle on the sidewalk.

Benjamin has $5000 in his bank account he spends $250 per month on car expenses using the money in his account Benjamin's friend Corrado has $2000 in his bank account he deposits $100 each month into his account for his college fund. *PLEASE REFER TO THE QUESTIONS IN THE PICTURE. THANK YOU!!!*
Answer: $5000 - $250x = y (Benjamin)
$2000 + $100x = y (Corrado)
Step-by-step explanation: Benjamin is spending $250 per month. So if number of given months is x his total spending in x number of months will be $250x. Whereas his initial amount in bank was $5000 and he is withdrawing $250 each month. So the remaining amount y spent on car expenses can be calculated with the equation as follows:
$5000 - $250x = y
Benjamin's friend Corrado is depositing $100 per month. So if number of given months is x his total deposits in x number of months will be $100x. Whereas his initial amount in bank was $2000 and he is depositing $100 each month which will add in initial amount to find y the current amount of money in bank. So the total amount y saved for college fund, can be calculated with the equation as follows:
$5000 - $250x = y

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!
